This is a tough one: My trips are generally 2 weeks in length, so I'm always 1) checking to see there are plenty of dive sites that an op doesn't repeat over and over, and 2) there are several things to do topside.
Aruba - has many wrecks (the Antilla is one of the largest in the Caribbean) that have swim-throughs; a few that I've never been to are said to be great dives but the ops don't go to them due to conditions. There can be drift diving towards one end of the island and regular boat dives on the other.
Grand Cayman: has several wrecks (the Kittiwake is pretty popular) and a lot of neat topography that offers swim throughs. As long as the conditions are good, you can dive different sides of the island - no shortage of dive sites as they advertise 365 dive sites for each day of the year.
St. Maarten: has some nice small wrecks - Gregory II was probably the most fun wreck I've gone through - lots of life inside and around it. Can dive on different parts of island which offers different scenery/topography. I would go to St. Maarten anytime, but overall diving isn't as good as what I've mentioned already. As @rick00001967 maybe tie that in with a day trip to Saba.
Dominican Republic: I dove in the small town of Sosua (probably where many Puerto Plata dive ops go.) Not too exciting, but I got wet. Bayahibe is where one has to go for the better diving - there are a couple of wrecks there.
Aruba: Pretty flat with a couple of big hills. Some pretty cool features along the shoreline.
Grand Cayman: Flat
St. Maarten/Saint Martin: Low mountains and hills and actually has lagoons and a salt flat.
Dominican Republic: mountains and desert area.
St. Croix: Has a botanical garden (often an event is happening like Mango Melee), casino, 2 small forts (one on each side of the island), sugar mill plantations, trip to Buck Island (national marine park with snorkeling trail), hiking to the lighthouse, and some nice places to snorkel, and depending on time of year, Carnival or the Christmas boat parade. There is also the Cruzan Rum Factory!!
Aruba: has some sites to see, but one can cover those (lighthouse, small museum, old church, a walk through the capital city) in a few days. Phillips Animal Garden is a shelter, but not very well kept, IMO. Several sites in the Arikok NP can only be seen via a tour (ATV, horses, etc.) There is also an Atlantis submarine if non-divers want to go under. The Balashi Beer distillery (tour) was closed when we were there.
Grand Cayman: The Turtle Farm has a great snorkeling lagoon. Seeing Hell only takes a few minutes. On the East End, there is a botanical garden that is nice as well as caves (not extensive, but still pretty cool) which can be toured. Starfish beach is pretty neat as long as starfish are still there. An evening beach dinner/party is fun. I want to say that there is a diving museum, but I haven't gone to it yet. A jet-ski tour (or some other tour) that takes you through the mangroves is different. There is also Stingray City where you can get in with the stingrays. There is also an Atlantis submarine if non-divers want to go under.
St. Maarten: Two sides of the island, one Dutch and one French for 2 different cultures. Nude beach on the French side (I haven't done that!) Catamaran tours go around the island. Think there are a couple of touristy things like a zipline and water slide. The Marigot Market (like a straw market) is on the French side. There is a super small fort (Fort Amsterdam) that can be hiked to - its out on a small peninsula, Dutch side and Fort St. Louis on the French side. Some great "Old Man" rums to be had there!
Dominican Republic: lots to do here. A tour through Puerto Plata is interesting. Rum factory tour was nice. Tram up to the "Christ the Redeemer" statue. Extreme (to me) water sport activity like sliding down waterfalls is available. As large as it is, my guess is that there are plenty of things to do on other sides of the island.
If I were looking for really interesting things to do, it would be Costa Rica - can't say anything about diving on the Caribbean side, but interesting things to do is 100x more than anything on an island. You can spend full days doing/visiting different volcanoes, hot springs, parks, hiking, sightseeing, etc......
St. Croix - Has several wrecks: 1 deep (Rosa Marie) at about 80-100' and 3 shallower that are generally done on the same dive. Man-made structure is the Frederiksted Pier which is usually listed as one of the top diving sites in the Caribbean (can shore dive it and should also be done as a night dive.) Canyons and walls can be found on other sides of the island which are not that far or hard to get to - some pretty neat topography. Nep2une Scuba is a good op by the pier.1. Lots of wrecks and other (man-made) 'structures' (swim-throughs, canyons, walls) at recreational depths (<40m), not just reefs

St. Croix: varied landscape - also has the "rainforest" (not a real rainforest, but very lush vegetation.) One could get lost driving through it. Mostly rolling hills with some amazing ocean views from the bluffs.2. Interesting landscape on land, i.e. volcano, jungle, mountains - not those flat, scrubby wind-swept planes with a palm tree every few miles

I think this is the toughest to answer since what's interesting to one may not be interesting to others and is there enough for a 10-12 day stay.3. Interesting things to do (not just beach-going or ATV rides)
